ATTACHMENT FOR PHONOGRAPHS, &c.

Specification of Letters Patent.

Patented Oct. 19, 1909.

I To all it may concern.

Be it known that I, GEoRcnF. PERRENOT,

I a citizen of the United States, residing at Yoakum, in the county of Dewitt and State of Texas, have invented certain new and use 'ful I-mprovemen ts in Attachments for Phonog'raphs, Graphophones, 8:0,; and I do declare the following to be a full, clear, and exact description-of the invention, such as willenable others skilled in the art to 'LWlllCll it appertains to make and use the same.

Thisinvention comprehends the construction: of a repeating. devicefor phonograplis or 'graphophones capable" of returning a reproducer of a'phonograph to. its starting position on a record.

vide a phonograph with means for returning a reproducer to its starting position and to automatically hold the reproducer out of engagement with its driving shaft.

With these and other objects in view this invention comprises certain novel constructions, combinations and arrangements of parts, illustrated in the accompanying drawings and particularly described in the specification and claims.

' In the drawings and specifications similar parts are referred to bylike numerals, in which,

Figure l-is'a side elevation showing my improved mechanism in its normal position; Fig. 2 is .a' side elevation showing my. im* proved mechanism in a raised position; Fig 3 is a plan. View; Fig. 4 is a transverse section taken .on line 4-4 of Fig. 1, and, Fig. 5 is a detail vertical sectional view taken on line 55 of Fig. 1.

In the drawings, lindrical phonographic machine comprising a base plate 1, on which are positioned a plurality of standard "plates 2, 3 and 4. The standard plates 2 and 3 support a driving mechanism 5, and are secured in place in any suitable manner, in this instance by I have illustrated a cy-.

. application filed December 26, 1903. Serial No. 469,213.

' horizontal rods 6. The usual shafts for the record and the reproducer are mounted on the standard plates. A cylindrical record 7 rotates on a record shaft'8, and a threaded shaft or worm 9 having connections with the driving mechanism connects with a reproducer arm 10, said arm carrying a re producer 11. The arm 10 is slidably mounted on two horizontal rods 12 and 13, and

the rod 12 isprovidcd with a spring 14 which exerts tension against arm 10..

' The arm 10 is provided with a movable half nut 15 arranged to engage the threaded shaft 9, and said nut is provided with a pin.

16 which extends laterally therefrom. When the nut 15 engages the threaded shaft '9, the reproducer 11 will be moved across the record 7, and this movement of the reproducer will compress spring 14.

My repeating mechanism comprises a verticalplate 17, formed with a guide 18, and a slotted projecting arm 19, said plate being secured to the standard plates 4, by means of a bolt passing through the slotted arm 19. The vertical plate 17 is preferably formed with a narrowed upper end portion 20, and a plurality of apertures 21. An arm 22, carrying a-hammer 22 on one of its ends,

and having the opposite end 24 bent at right angles to its body portion, is pivotally and adjustably mounted upon the plate 17 by v 4 means of a bolt 25 which isarranged to extend through apertures21. End 24 of arm 22 is provided with a. lateral pin 23, and a second pin 26 projects laterally from the plate 17 and is engaged by the arm 22.

The arm 22 is connected by springs 27 and" 28 to the plate 17 and to the bolt 25, which are adapted to quickly move the hammer 22 downwardly with suilicient force to disen gage the bolt-nut from its worm shaft. Should it be desired, one of the springs 27 or 28 maybe dispensed with, by increasing the strength of the retained spring. A lever 29formed with a slotted end 30 is pivotally mounted on the plate17 bya bolt 31. A. trip lever 32, formed with an aperture 33 and a" V-shaped end, is mounted on lever 29 beyond the pivot bolt 31 and is adapted to engage arm pin 23 on lever 24 toraise the hammer 22 as will be hereinafter described.

The lever 32 is held in a substantially ver-' tical position by means of a spring 33, said spring having one of its ends secured to the end of lever 32 and its opposite end secured Int ' tion, the record 7 will be rotated on the shaft to the middle portion of lever 29. Lever 29 is engaged by a horizontal bar 34: which is movable on the guide 18 and on a second guide 35 which is formed on'reproducer arm 10. Bar 34 has one of its ends secured to the slot-tedv end of lever 29 by a bolt 36, saidbplt having its head projecting through said slotted end so as to securely connect lever29 to bar 34. Bar 34: is formed with a plurallt-y of apertures 37 through which pins 38 and r 39 extend. I

When the driving mechanism 13 set in mo- 8 and the reproducer 11 will be moved across said recordby means of the revolving shaft or worm 9. As the reproducer moves across the face of the record guide 35 will engage pin 39 on 'bar 34 thereby causing said bar to move with it. press spring 14, move lever-s29 and 32 so that the V-shaped end of lever 32 will engage pin 23 on arm22, thereby raising the.

hammer 22 The hammer 22 willbe held in its raised position by lever 32 until the reproducer has completely crossed the rec'- 0rd, and when this occurs,,hammer 22 will I be released by the lever 32 and thrown downwardly by the springs 27 and 28to strike pin 16 which will then be in line of engagement and thereby move nut 15 out of engagement with shaft 9, and whenthis disengagement occurs, spring 14 will au to matically. return the reproducer 11 to its starting position. As the reproducer begins to move to its starting position, guide will engage pin 38 of arm. 34 and thereby move levers 29 and 32 to their normal position. When the rep'ro'ducer arm 10 arrives at'its starting position, it will remain stationary unless the nut 1.5- is brought into engagement with shaft 9. This action is ac complished by means of a-anovable arm 40 which projects from standard plate 3 and by engagement with nut 1.5 moves the same against shaft 9. In case it is not desired to have the record repeated the arm 40 is moved on its pivot 41 so that the nut 1.5 will not be engaged by said arm, when the machine may be stopped.

My improved repeating device may be attached to any cylindrical phonograph by means of detail modifications.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without This movement will. c0min what manner the same is to be performed, I declare that what I claim and desire to secure by Letters-Patent is 1. In a device'of the class described, in

be engaged by the reproducer, levers moved by the rod, a hammer operated bythe rod and means for returning the reprodueer to its original position operated bythe movement of the hammer.

3. In a device of the class described; in combination witli'a phonograph, comprising a record, a reproducer-and mechanism therefor, a rod movable horizontally by the reproducer, levers connected with the rod, a hammer engaged by the levers, a movable nut carried by the reproducerengaged by the hammer, and a spring for returning thereproducer to its original position.

4. In a device of the class described, in combination with a phonograph, comprising a reproducer, a record and mechanism therefor, a plate arranged to be mounted on the supports of the phonograph, a hammer arm pivotally mounted on the plate, means for adjusting the hammer arm on the plate,

a slotted lever, a lever carried by the slotted lever, a rod connected to the slotted lever and arranged to be engaged by thereproducer, means for disconnecting the repr0- ducer from its driving shaft, and a spring for returning the reproducer to its orlginal position.

5. In a device of the class described, the

? combination with a phonograph, compris ing a record, a reproducer, and mechanism therefor, a movable rod engaged by the reproducer, a slotted lever engaged by the rod, a lever carried by the slotted lever and arranged to engage a hammer, a hammer en- 1 gaged thereby,springs for controlling the hammer, means for disengaging the reproducer from its drivingshaft, a spring for moving the reproducer to its original position, means for supporting the rod, the levers and the hammer, and a movable arm for limiting the movement of the reproducer.

In testimony whereof I have hereunto set my hand inpresence of two subscribing wit-
